My newest Para is my LDA 12.45 with a 3.5" barrel. It's a Para USA and covered by the lifetime warranty. They replaced the single spring recoil system on it with a dual spring set up very much like what's on the 3" barreled pistols. I think my P10.45 is a Para-Ordnance and not covered. My 13+1 frame from the first year they made them is definitely not covered. All the parts from a P14.45 can be stripped from the frame and used on a regular 1911 except for the magazine (of course), the mag release, the trigger, and the grips. If there's anything else that can't be used I can't think of it at this time.
